已知数组a：

array (  0 =>   array (    'po_num' => '20131227-000008102',    'plant' => 'JQSP',    'get_date' => '2013-12-27',    'cust_no' => '12654172',    'total' => '225',    'snp' => '15',    'mount' => '15',    'lp_no' => 'P000000D',  ),)

处理程序如下：

$t = 225;$k = 0;foreach($a as $v) {$t1 = $v['total'];$v['total'] = $t1 % $t;$res[$k][] = $v;$t1 -= $v['total'];while($t1 >= $t) {$v['total'] = $t;$t1 -= $t;$res[++$k][] = $v;	}	}$res = array_reverse($res);print_r($res);

得到的结果：

Array(    [0] => Array        (            [0] => Array                (                    [po_num] => 20131227-000008102                    [plant] => JQSP                    [get_date] => 2013-12-27                    [cust_no] => 12654172                    [total] => 225                    [snp] => 15                    [mount] => 15                    [lp_no] => P000000D                )        )    [1] => Array        (            [0] => Array                (                    [po_num] => 20131227-000008102                    [plant] => JQSP                    [get_date] => 2013-12-27                    [cust_no] => 12654172                    [total] => 0 //产生了为0的项                    [snp] => 15                    [mount] => 15                    [lp_no] => P000000D                )        ))

既然是整除，那么结果应该只有一项，如何修改代码让其只有非0项生成？

回复讨论(解决方案)

想复杂了吧，你想要什么结果，或者可以换一种思路。
